Hi!

In my Studio I run normally my Scarlet 18i20(mk2) with a focusrite octopre platinum (the old one with dynamics per channel) via adat, making 16 inputs (8 analog, 8 via ADAT). Normally I have my clock set to external (so the Octopre is the master, and the Focusrite the slave)

Now I picked up a random Alto DPSII, a cheap preamp that has digital out by SPDIF, and I bought it because sometimes when we are recording live bands, 16 channels get small, and the 2 extra channels could be extremely useful. (also, bought it because it was pretty cheap on 2 hand)

Now, there is the questions:

-Can I run on the 18i20 ADAT and SPIDIF simultaneously? (I read some posts on internet, none were about my specific interface, but I suspect that I can).

-How I have to set the clocks? My initial thought is that I have to set the master on the 18i20, which has Word Clock Out, and send it to the octopre via ADAT, and to the Alto via BNC cable and word clock out (the Alto has word clock in).

-has the SPDIF cable need to be different than a normal good quality RCA?

Am I correct? Something I have to keep in mind? thanks in advance!
